Short answer: the Ascend Acoustics HTM-200SE2. It ranks #7 of 179 bookshelf speakers by sound quality, rated 4.3/5, at $368. The Polk T15 ranks #164, rated 1.9/5, at $149, $219 cheaper, which does not close the gap in sound quality.
Why pick the Polk T15: A very affordable bookshelf speaker for near-field desktop use. The tradeoff: Spinorama analysis shows a deep on-axis dip from 3 to 6kHz in the upper mids and lower treble, likely from tweeter-woofer phase cancellation directly on-axis.
The Ascend Acoustics HTM-200SE2 is the more accurate choice. A compact sealed speaker with two small woofers, highly accurate sound and very wide dispersion, ideal with a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 4.98 against 0.34 for the Polk T15. The tradeoff: Limited bass is the main tradeoff, measuring 87.9Hz at -3dB, 71.8Hz at -6dB, and 51.3Hz at -12dB; its preference score falls to 4.98 without a subwoofer.
Buy the Ascend Acoustics HTM-200SE2. It is rated higher for sound quality, and the $219 saving on the Polk T15 is not enough to make up the difference.
